" A work by a master in the science who understands the significance 

 of every phenomenon which he records, and knows how to make it reveal 

 its lessons. As regards its value there can scarcely exist two opinions. As 

 a text-hook of the nistorical phase of palseontology io will be indispensable 

 to students, whether specially pursuing geology or biology ; and without 

 it no man who aspires even to an outline knowledge of natural science can 

 deem liis Ubrary complete." — The Quarterly Jcmrnal of Science. 



" The Professor of Natural History in the University of St. Andrews 

 has, by his previous works on zoology and pal93ontology, so fully estab- 

 lished his claim to be an exact thinker and a close reasoner, that scarcely 

 any recommendation of ours can add to the interest with which all students 

 in natural history will receive the present volume. It is, as its second title 

 expresses it, a comprehensive outline of the principles and leading facts of 

 palseontologioal science. Numerous woodcut illustrations very delicately 

 executed, a copious glossary, and an admirable index, add much to the 

 value of this volume?' — Athenmum.
